Objectives:This study was designed to investigate the effects of SuJeom-san(SJS) extract in rats with caerulein-induced acute pancreatitis (AP).
Methods:We examined changes of pancreatic weight, histological, immunohistochemical and gene expression of cyclooxygenase (COX-2). Thirty-six adult male Sprague-Dawley rats were divided into six groups as follow: normal(Nor), caerulein-induced (Con), caerulein + cefotaxime sodium(CT), caerulein + SJS 3 mg/kg(SJSA), caerulein + SJS 6 mg/kg(SJSB) and caerulein + SJS 12 mg/kg(SJSC) groups. Pancreatic tissues of rats from all groups were removed for histological observation and light, and electron microscopic examination. Platelet activating factor(PAF) and Interleukin-6(IL-6) levels were determined spectrophotometrically.
Results:The ratio of pancreas/body weight was significantly(p<0.05) increased in the Con compared with Nor, but significantly(p<0.05) decreased in SJSA, SJSB, SJSC and CT groups compared with Con. Caerulein administration significantly increased(p<0.05) the levels of amylase, but SJSA, SJSB, SJSC and CT significantly(p<0.05) reduced the levels of these enzymes. The levels of platelet activating factor(PAF) increased in Con compared with Nor, but decreased in SJSA, SJSB, SJSC and CT groups compared with Con. Interleukin-6(IL-6) levels increased significantly in all groups compared to Nor at 6 hrs, but significantly(p<0.05) reduced in SJSA, SJSB, SJSC and CT groups compared with Con at 24 hrs. The levels of tumor necrosis factor(TNF)- levels increased in all groups compared to Nor at 6 hrs, but significantly(p<0.05) reduced in SJSA, SJSB, SJSC and CT groups compared with Con at 24 hrs. The COX-2 positive materials were observed in the pancreas of the Con, but these positive materials were decreased in the SJS extract treatment group.
Conclusion:SJS is potentially capable of limiting pancreatic damage during AP by restoring the fine structure of acinar cells and tissue; therefore, we conclude that SJS may have beneficial effects in the treatment of caerulein-induced AP.
